I've recently been involved in a thread on another list that dealt with the problems of programming with threads. There are people approaching the problems (including deadlocks) by providing constructs for threading that mean you can't write such code. At least, that's the idea. http://www.jot.fm/issues/issue_2004_04/article6 was posted as one such solution. I'm not convinced it works, but the paper only discusses half the solution. <mike -- Mike Meyer <[EMAIL PROTECTED]> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information. -- http://mail.python.org/mailman/listinfo/python-list
